Boss-COUPLING.

To allwlwm itma'y concern: i

Be it known that I, WILLIAM T. Born, a

citizen of the United States, residing at Ottumwa, in the county ofWapello and State of Iowa, have invented a certain new and usefulHose-Coupler, of which the following is a specification.

The object of my invention is to provide a hose coupling device ofextremely simple, durable and inexpensive construction by which a hosemay be connectedwith a h"- drant quickly and easily without the use of awrench or other tools.

A further object of my invention is to rovide such a device by which thecoupling oint is made water tight.

My invention consists in the construction, arrangement and combinationof the various parts of the device, whereby the objects contemplated areattained, as hereinafter more fully set fort-h, ointed out in my claimsand illustrated in t e accompanying drawings, in which:

Figure 1 shows a side elevation of a fire hydrant equipped with myimproved hose coupler. Fig. 2 shows a vertical, sectional view ofmy hosecoupler, and Fig. 3 shows a detail sectional View on the line 33 of Fig.2.

In the accompanying drawings, I have used the reference numeral 10 toindicate an ordinary compression fire hydrant. It is to be understoodhowever that my coupling device may be used with other forms of hydrant,or for connecting sections of hose or The hydrant 10 is provided withopenings for the discharge of water. Around the edge of the openingsannular flanges 11 are formed on the hydrant 10. The annular flanges 11are screw threaded on their inner surfaces.

My improved hose coupler comprises a tube 12 screw threaded at one endand designed to be received at said end into said annular flange 11. Thetube 12 is provided at its other end with an annular flange 13, formedon said tube 12 at right angles to the longitudinal axis thereof. Thelower half of said flange 13 is constructed with an extension 14 atright angles to said flange 13.

and extending away from the body of said tube 12. The extension 14 isprovided with an extension 15 adjacent to the central axis of the tube12, the flange 13 and the extensions 14 and 15 forming a semicircularchannel. The inner surface ofthe extension 15 Speeiflcation of LettersPatent.

is provided with an annular flange 18, the

lower half of which is designed to be received within the opening formedby the flange 13 and the extensions 14 and 15, and the upper half ofwhich is designed to' be held adjacent to the upper half of the flange13. The lower half of the annular flange 18 is slightly beveled on theside adjacent to the body of the tube 17 to fit the beveled surface ofthe extension 15. Hinged at one side of my hose coupler to the flange 13and the extension 15 is a semi-circular metal channel or covering device20 designed to fit closely over the upper half of the flanges 18 and 13,and to serve as a cap therefor. The outer surfaces of the flanges 13 and18 are slightly beveled from the port-ion of said flanges adjacent tothe bodies of the tubes 12 and 17 to the outer edges of said flanges.The inner surfaces of the sides of the covering device 20 are slightlybeveled to fit the flanges 18 and 13. On the inside of the coveringdevice 20 in the bottom of the channel or groove formed therein, I placesuitable packing material 21 for the purpose of forming a tight jointwhen the covering device 20 is closed over the flanges 1.3 and 18. Onthe outer side of the flange 13 and the extension 15 opposite the jointwhere the covering device 20 is hinged, is formed a lug 22. On thecovering device 20 at a point above and adjacent to the lug 22 when thecovering device is in its closed position is formed a lug 23. Pivotallysecured to each side of the lug 23 are arms 24 which extend to a pointslightly below the lug 22 when the covering device 20 is in its closedposition. Pivotally secured between the arms 24 at their lower ends, isa locking lever 25 by which the covering device 20 may be tightly lockedover the flanges 13 and 18.

I preferably secure to the hydrant, a

chain 26 having at its free end a disk 27 designed to be placed in thegroove formed by the flange 13 and the extension 15 to cover the openingin the hydrant when the hose is detached therefrom. As will be seen mycoupling device, the disk 27 is moved from the groove formed by theflange 13 and the extensions 14 and 15, and the covering device 20 israised. The lower half of the flange 18 on the tube 17 is inserted insaid groove and the covering device 20 is closed and locked by means ofthe lever 25. The construction of the beveled surfaces heretoforedescribed, provides my coupler with a tighter joint than could otherwisebe effected. By means of the packing material 21 substantial resiliencyof the covering device 20 is provided to permit the locking by means ofthe lever 25.

The advantages of my device are found in its simplicity of construction,in its durability, and in the small cost for which it may be made.

My hose coupling device is particularly adapted for use by firemen orothers to whom speed in making a coupling is important. Ordinarily inmaking a coupling it is necessary to unscrew a plug at the fire hydrantand to screw into the opening an attachment on the end of the hose. Thesaving in time that is accomplished in using my device is obvious.

I claim as my invention:

1. An improved hose coupling comprising a tube designed to be secured toa hose and hydrant, an annular flange formed on one end thereof, asemicircular channel formed on the lower half of said flange, the innersurface of said channel farthest away from the body of said tube beingslightly beveled from the bottom of said channel to the up per edgethereof, a tube designed to be secured to a hose, an annular flangethereon, the lower half of said flange being slightly beveled to fit thebeveled inner surface of said channel, said flanges being constructedthe sides adjacent to the bodies of said tubes,

the inner surfaces of said second channel being beveled to fit thebeveled surfaces of said annular flanges, packing material in the grooveof said second channel.

2. An improved hose coupling comprising a tube designed to be secured toa hose and hydrant, an annular flange formed on one end thereof, asemicircular channel formed on the lower half of said flange, the innersurface of said oh nel farthest away from the body of said t be beingslightly beveled from the bottom of said channel to the upper edgethereof, a tube designed to be secured to a hose, an annular flangethereon, the lower half of said flange being slightlybeveled to fit thebeveled inner surface of said channel, said flanges being constructedwith annular grooves registering with each other and designed to receivepacking material, packing material in said grooves, a semicircula1channel hinged to one side of said first semicircular channel anddesigned to fit closely over the upper half of said annular flange, theupper halves of said annular flanges being slightly bev eled on thesides adjacent to the bodies of said tubes, the inner surfaces of saidsecond channel being beveled to fit'the beveled surface of said annularflanges, packing material in the groove of said second channel, a lug onsaid first channel opposite the hinged point, alug on said secondchannel above said first named lug when the coupler is closed, armspivotally secured on each side of said second lug extending downwardlyon each side of 'said first lug to a point below the same, and a lockinglever pivotally secured between the put ends of said arms.
